Hello

I'm having problems with my computer. When I turn on my PC, it will work fine for a few minutes, but then my secondary monitors will turn black and a few seconds later my main monitor will turn white and have these weird horizontal lines going through it.

And after a few minutes of have a video game open(starcraft 2, COD, etc) I will get a blue screen of death.

I've replaced the power supply and hard drive. I'm thinking it's the graphics card.

Please help.

Thanks!


By the way, these are my specs:
Asus motherboard
Quad core intel i7 sandy bridge processor
ATI radeon 6970 diamond edition
Western digital 1TB hard drive
Vengence 8GB RAM
1200 watt power supply
